Computer-based training for safety: comparing methods with older and younger workers
Abstract
INTRODUCTION: Computer-based safety training is becoming more common and is being delivered to an increasingly aging workforce. Aging results in a number of changes that make it more difficult to learn from certain types of computer-based training. Instructional designs derived from cognitive learning theories may overcome some of these difficulties.
METHODS: Three versions of computer-based respiratory safety training were shown to older and younger workers who then took a high and a low level learning test.
RESULTS: Younger workers did better overall. Both older and younger workers did best with the version containing text with pictures and audio narration.
DISCUSSION: Computer-based training with pictures and audio narration may be beneficial for workers over 45 years of age.
IMPACT ON INDUSTRY: Computer-based safety training has advantages but workers of different ages may benefit differently. Computer-based safety programs should be designed and selected based on their ability to effectively train older as well as younger learners.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
